I finished the spraying today. About 40 ounces of laqcuer....hmmmm
2 coats vinyl sealer, probably one sanded off

10 coats thinned 20% then level sanded
2 more coats then
Last coat 50/50 with bit of retarder.

It looks good. Pretty flat. Won't take very much final leveling once cured. I'll let it cure at least a month, maybe two.

Good looking Kevin. That koa is beautiful ideed. You Americans are lucky with that national wood. Over here it is hard to get. And if you do, it is very very expensive.

Thanks Herman
Expensive here too.
Better price if you get it from a guy in the Hawaiian Islands.
I got all this a few years ago when it was not so bad.

UPDATE. HORROR!

So I saw something this morning that struck me with Horror. Or at least it made me sad.

The guitar has been hanging in my garage shop for two months since spraying. It has been fine up to at least a week ago. But today I looked at it and found the top lacquer has cracked with multiple cracks from top to bottom and I'm guessing they go through to the wood.
Also the front and back of the headstock have some cracking, but more minor.
Interesting the neck shaft and heel, and the back and sides have no cracks. It is cold out there but we have not had freezing temperatures. Humidity had been high....a bit higher than when I sprayed. So I don't know if it's temp changes or humidity changes or both. I've never had it happen before. I don't believe I'm any thicker on the lacquer then usual for me. I think I measured .010" when I removed the bridge mask. With leveling it usually ends up .005" or a smidge less thick.

I figure I can wait till warmer weather and shoot it with straight thinner or highly thinned lacquer and melt it back together????? I'm hoping!!!!

Any ideas, thoughts or suggestions from the gang here would be welcome and helpful. Mohawk Nitro lacquer

I think the picture shows some of it.
